Sumario

arine invertebrates, the descendants of one billion years of evolutionary history, are the most abundant creatures in the ocean. In the Sea of Cortez, packs of Humboldt squid make night-time raids from the deep to co-operatively hunt sardines. Beneath the permanent Antarctic sea ice of McMurdo Sound, sea urchins, red sea stars and nemertean worms are filmed scavenging on a seal carcass. A fried egg jellyfish hunts amongst a swarm of Aurelia in the open ocean, spearing its prey with harpoon-like tentacles. In the shallows off South Australia, hundreds of thousands of spider crabs gather annually to moult. Large male cuttlefish use flashing stroboscopic colors and strength to win a mate, whereas smaller rivals rely on deceit: both tactics are successful. A Pacific giant octopus sacrifices her life to tend her single clutch of eggs for six months. Marine invertebrates have a lasting legacy on land too - their shells formed the chalk and limestone deposits of Eurasia and the Americas.
